Btwin Rockrider 500s Full Suspension Mountain bike £239 Decathlon

36
Found 8th May 2016
Saw a post from a long time back. That time the "real" mountain bikers commented the back side out of it. So for the "pretend" bikers like me who like a trail followed by just enough of the rough stuff this is a great buy compared to their new model in particular the hard tail at the same price point.

The shocks are Btwin but bases around the suntour SCM. Why is it better. Lock out and 120mm travel. The SCT on the hard tail and the Carrera going melty hot this week do not have this. So Bouncy time on the flat stuff.

Rear derailleur is a x4 vs x3 on the hard tail.

OK so no 27.5 wheels and yes the difference will be all so noticeable and may add one minute to your ride. But a 26" has served me well for years.

Wire disc brakes but Hayes brand. Not too shabby and standard mounts so throw hydraulics on when you become hardcore.

Lifetime warranty on the frame. 2 year warranty on the parts. Free 3 month service. Oh and decathlon points

Edinburgh have a large in stock the website has XL which is good for 6ft1 up. 5ft10 ish for the large.
Btwin from Decathlon are great bikes at bargain prices... Mines still going great after 4 years of riding...Hot from me!
only real concern I would have for this is weight, but to get a good full sus your looking at a grand, and most of that is just for the name.

cable brakes don't concern me at all, I've seen lots of badly setup hydraulic brakes that would struggle to stop a kiddy bike. look to upgrade pad compound before anything else

heat added, but I will say that most peoples needs off-road will be fulfilled by a hardtail.

At that price why complain?

From experience I'd really not want cable disc brakes, I've got some pretty high end Tektro on my touring bike, and they're far worse than any of my road bikes dual pivot brakes or centre pull, though I suppose the positive side, it's absolutely impossible to skid on skinny tyres because of it.

For a mountain bike where the tyres have more grip, you can really benefit from decent brakes, I'd not touch anything but (well setup) hydraulic discs, it's not worth the weight penalty or the complexity of maintenance for poor performance of the cable ones.

I guess if the weight penalty (which isn't as bad as most cheap full suspension bikes) or lack of hard tails with similar specs for the money, this might be ok for the price, certainly I've got a suntour with lockout, and it is handy especially if you're using the bike mostly on road and soft off-road.

​I can say flat out the wheels stop without lock up. Hydraulic will sharpen it but pure stopping will be negligible.

Oh and the weight. Light bike. Less effort. Like being on a weights bench using the lightest weights. all relative.
What's better this or the carrera vengeance

What's better this or the carrera vengeance



​Looked at the two. Shock lock out and the decathlon warranty swung me
COLD . No rock shox
I bought the carrera a few days ago and they say it weighs around 13kg . I took it out for its first spin nothing to mad. after 7 miles I thought it was good bike . the down side is no lock shocks but to be fair it didn't bother me. the thing that did was weight... I am a occasional MTB rider but i ride a road bike more and the one thing I noticed about the carrera was its weight . it is around the a average I have been told . the btwin looks like of weighs more with 26" wheels . just for the weight I would go for the carrera

Hands down prefer a decent set of Avid BB7 cable disc brakes than any el cheapo tektro hydraulics any day of the week.
Does the rear shock have lock out?
Cold ❄ Full suss for under 250! Get s similar priced hardtaill from chainreaction cycles on offer. You will notice the difference in ride quality. Wouldn't touch this for free. 500 should be minimum spent on a mtb to last and enjoy riding.

​The rear shock is as much use as some lactose intorrelant with an unstoppable flatulent behind. Unstoppable and unlockable
Kosher deal, heat from me
My mountain bike has cable brakes... and not even cable disc brakes! Cost like £800 back in then. Still does a reasonble job though and sure helps keep the weight down.
i used to like to ride straight over potholes with dual suspension bike - so no dangerous swerving in traffic

so it protects your wheel from knocks and your bum from bump

I really feel for those 90% + of people who own sub £500 bikes for all the pain and suffering they are experiencing. It's a surprise that any of them bother cycling seeing as they can't possibly be enjoying it.

They can't bear the shame of being seen on a sub £500 bike, so simply don't take them out.

Admittedly haven't got experience of the BB7s, but I was so relieved to get rid of the BB5s that came on my Hardrock. Went to some cheapy Shimano hydraulics from CRC and the difference is night and day.

My most recent purchase was a Pinnacle Arkose 2 gravel bike/cross bike which comes with Tektro Hylex and the stopping power on those is phenomenal.

Couldn't go back to cable discs and constant tinkering. I know the BB7 has double sided pad adjustment so that might make it more liveable than the BB5s.

Heat added for a 26" bike, there's not much love left for them online

Missing something, halfords vengeance went hot (my vote) because it was £156 which is much cheaper than this. 10% code, 10% British cycling, 10%ish gift vouchers and 3% poss quidco.

Almost bought it but they killed the code 1 day later. Too slow. But after looking at it in store, it was a bit meh.

Your right. But, it does screw tight. KInd of locks out and does not bounce around. For around £40 you can get a Rock Shox Air on Ebay. Plan in a few months
Cheap nasty built bike with cheap brakes and cheaper gears - all which will start causing problems after light usage. Save your money. You just won't buy a bike at this price built to last (not new anyway)

I bet the majority of hot votes are by people clueless to mountain biking.

This is not a good MTB, avoid.

BB7's are worlds apart from the BB5's...the fact that you can very easily adjust on a trail, takes seconds, no messing around with bleed kits and hoses make them more liveable than cheap hydraulics in my opinion. More expensive hydraulics would provide better modulation and be lighter admittedly, but BB7's do not compare with BB5's and are recommended on many a biking forum for those that do not want faffing.
I too will add that a full sus at this price point will be a bit of a missed opportunity. Full sus is designed for some fairly heavy use over rough terrain going downhill.

If you were into that sort of thing, then you would undoubtedly be looking to pay more to get a bike that would give you the performance and reliability you'd need hurtling down a hillside. That bike would still be heavy; Full Sus bikes aren't that concerned with weight (cos it's all down obvs).

On the other hand, if you were buying this for light trails or just rolling around as a leisure bike, you would be far better served by a hardtail which will give you ample damping through a front fork alone and will be far lighter. This means going up as well as down will be a)actually doable without giving yourself a hernia and b)fun!

Another point to note - suspension = lost energy. So, full sus will suck up more of your efforts than a hard tail, and a hard tail will suck up more of your energy than a fully rigid bike. Some suspension is lockable to negate this somewhat when rolling along or going up. Bear this in mind when thinking what you might use the bike for.

In summary, you can get some excellent value hardtail mountain bikes or hybrid bike at this price point, but, a full-suspension machine is a very technical and specific tool designed for doing one thing only - down hill fast! An entry level machine is going to be sitting a few more hundreds above this (ironically perhaps, the Decathlon full-sus bikes do get listed as best entry level by some sites, just at around the £6-700 mark)

I would worry that someone interested in getting into bikes or mountain biking would be put off from the sport if they were to get this.

Hope this helps.
For anyone wanting an introduction to mountain biking the Rockrider 520 on their website for this price that is front suspension only would be a far more sensible choice.

So what is in your cycling 'criteria' then? Does this include anyone that buys a £500 + bike that has been reduced to £3-400 because it is on offer or last years model, or anyone that buys a second hand one. (_;)

A little bit of the mechanics on this bike. Key to any full suspension not being an energy looser is the location of the main pivot point. On this bike it is in the "ideal" location meaning in the big gears it reduces bobbing while in low gears it will push the wheel down into the dirt. Have a look at some of the "pro" machines.

Decathlon are the Ikea of sports shops. Spend alot on R&D, then stack them high sell them low. Volume wins for them.

Got mine (Vengeance) early today for my 10yr old daughter - nice to have 14" frame with this spec. She won't have a clue about no lockout of naff fork - superb for her to use on canal and many forest paths in Scotland.

I agree with the sentiment, but many xc bikes are full suss as are enduro and they both involve going up and down. I doubt many people buying these will be doing anything serious, apart from bumping up kerbs and cycling on the odd rough path.
Could probably get a Voodoo Bizango for a hundred quid more, someone has posted something up on here in the last week or so.

Its been voted hardtail of the year and is a much better option than this.

Forget full suss unless your looking at spending a grand.

I feel you have missed the irony in my reply. I was attempting to ridicule the "500 should be minimum spent on a mtb to last and enjoy riding" comment.
